Struct PromptValidator 

pub struct PromptValidator;

Validates prompts against configurable rules and detects injection attacks.

Implementations

impl PromptValidator

pub fn new() -> Self

Create a new validator.

pub fn validate( &self, prompt: &str, rules: &[ValidationRule], ) -> ValidationReport

Validate prompt against each rule, returning a ValidationReport.

pub fn detect_injection(prompt: &str) -> Vec<(InjectionPattern, f64)>

Detect injection patterns in prompt, returning (pattern, confidence) pairs.

pub fn estimate_tokens(text: &str) -> usize

Estimate token count using the ~4 chars/token heuristic.

pub fn check_repetition(text: &str) -> f64

Compute the fraction of repeated 3-grams (words) in text. Returns 0.0–1.0.

pub fn check_language(text: &str, expected: &str) -> bool

Simple language heuristic using character frequency analysis.

For expected = "en" it checks for a high ratio of ASCII letters. For any other value it always returns true (not implemented).

pub fn safety_score(issues: &[PromptIssue]) -> f64

Compute a safety score from 1.0 (no issues) down to 0.0 using weighted penalties.

pub fn suggest_fixes(issues: &[PromptIssue]) -> Vec<String>

Generate actionable fix suggestions for a list of issues.

pub fn sanitize(prompt: &str) -> String

Remove detected injection patterns from prompt, returning a sanitised copy.

pub fn batch_validate( &self, prompts: &[&str], rules: &[ValidationRule], ) -> Vec<ValidationReport>

Validate a batch of prompts against the same rules.

fn default() -> PromptValidator

Returns the “default value” for a type.
